I hope it's okay to post this here! This website claims to send a free pedometer if you fill out a short survey. I just filled it out today so I don't know yet the validity of their claim, but I figured I would post it for everyone anyway.

One thing I would like to note is that pedometers are fine but you might get annoyed with a cheap/free one. I had a pedometer that I believe I got free and it kept resetting itself and seemed pretty inaccurate. I then got an Omron pedometer and it worked beautifully. I'd recommend that if you want a pedometer that you invest in one although you can try a free one to see how well it serves you.
